First Claim
1. An apparatus mounted on a vehicle to protect a passenger using a graphic light projection, the apparatus comprising:
- a first detection unit detecting an opening of a vehicle door;
a second detection unit detecting a boarding of a boarding person or an alighting of an alighting person;
a side step driving unit driving a side step;
a light projection unit mounted to a side of the side step and projecting a boarding protection graphic light or an alighting protection graphic light;
a third detection unit detecting the boarding person located within a predetermined distance from the vehicle; and
a control unit controlling the side step driving unit to pull out the side step set within the vehicle when the first detection unit detects the opening of the vehicle door, and controlling the light projection unit to project the alighting protection graphic light when the second detection unit detects the alighting of the alighting person,wherein the control unit controls the light projection unit to project the boarding protection graphic light when the third detection unit detects the boarding person and then the side step driving unit to pull out the side step set within the vehicle, when the boarding person detected by the third detection unit is determined to be within the predetermined distance from the vehicle and the first detection unit detects the opening of the vehicle door.
